Recently, I was tinkering around with an old air conditioning circuit board which was used to control a BLDC (Brushless Direct Current) motor for the fan when I found that tracing the circuits proved to be a bit more complicated […] ↓ Read the rest of this entry…
The movable gantry cnc machine that I am making would have a bigger working area than my previously made movable bed cnc machine. Therefore, using a drag knife to cut thin pieces of cardboard, plastic sheet and similar materials had […] ↓ Read the rest of this entry…
